Data Migration & Reconciliation Testing
Overview
Data Migration and Reconciliation Testing confirms that information moved between systems is complete, accurate, correctly transformed and usable in the target environment. It validates counts and values as well as relationships, history, business rules and the operational processes that depend on migrated data.
How it works
We analyse source-to-target mappings, define reconciliation controls, profile source data, test extraction and transformation logic, run trial migrations, compare row counts and field values, verify relationships and rejected records, test incremental changes and cutover, and produce signed evidence for unresolved exceptions.
Why Choose Us
- Reconciliation combines aggregate checks with record-level and business-rule validation.
- Trial runs expose source-data and mapping problems before the final cutover window.
- Exceptions are quantified and assigned rather than hidden inside overall success percentages.
Common Deliverables
- Source-to-target mapping review
- Migration validation and reconciliation rules
- Trial and cutover execution results
- Mismatch and exception register
- Migration acceptance report
Benefits
- Lower risk of migration-related data loss
- Faster and safer cutover decisions
- Clear evidence of transformation accuracy
- Reduced post-migration reconciliation effort
